An estimated 41.3 million travelers are expected to hit the nation’s highways for the holiday weekend, which is a 4.3% increase over last year. Travel is going to be hazardous with both rain and snow, causing slick roads.

The Thanksgiving holiday is one of the busiest travel times in the United States, with more than 46 million Americans expected to make trips between Wednesday and Sunday, travel group AAA said. More than 89 percent will travel by car, it said.
